Morpho-genetic variability of native and adventitious populations of the Brephulopsis cylindrica (Gastropoda, Pulmonata, Enidae)

The population structure of the terrestrial mollusc Brephulopsis cylindrica (Gastropoda, Pulmonata, Enidae) in the native area (Crimea Peninsula) and out of its borders (two adventive groups in the city of Belgorod) was studied on the basis of conchometric characteristics and analysis of polymorphic allozyme loci. For all the morphometric parameters statistically significant differences were found between the studied groups. In all studied populations a high level of intra-population genetic variability was revealed ( Fit = 0,401). At the same time, the considerable variability of the conchological parameters and the high level of allelic polymorphism at a number of loci identified in adventitious colonies create the prerequisites for successful adaptation to new conditions and further expansion of the species range in urbanized areas.

Abstract Khasi mandarin (Citrus reticulata Blanco) is a commercial mandarin variety grown in northeast India and one of the 175 Indian food items included in the global first food atlas. The cultivated plantations of Khasi mandarin grown prominently in the lower Brahmaputra valley of Assam, northeast India, have been genetically eroded. The lack in the efforts for conservation of genetic variability in this mandarin variety prompted diversity analysis of Khasi mandarin germplasm across the region. Thus, the study aimed to investigate genetic diversity and partitioning of the genetic variations within and among 92 populations of Khasi mandarin collected from 10 cultivated sites in Kamrup and Kamrup (M) districts of Assam, India, using Inter-Simple Sequence Repeat (ISSR) markers. The amplification of genomic DNA with 17 ISSR primers yielded 216 scorable DNA amplicons of which 177 (81.94%) were polymorphic. The average polymorphism information content was 0.39 per primer. The total genetic diversity (HT = 0.28 ± 0.03) was close to the diversity within the population (HS = 0.20 ± 0.01). A high mean coefficient of gene differentiation (GST = 0.29) reflected a high level of gene flow (Nm = 1.22), indicating high genetic differentiation among the populations. Analysis of Molecular Variance (AMOVA) showed 78% of intra-population differentiation, 21% among the population and 1% among the districts. The obtained results indicate the existence of a high level of genetic diversity in the cultivated Khasi mandarin populations, indicating the need for preservation of each existing population to revive the dying out orchards in northeast India.

AbstractThis paper compares findings on the distribution of support networks in the City of Liverpool and in rural communities in North Wales. It demonstrates that while support network type is highly correlated with a wide range of demographic and social variables in both urban and rural samples, the nature of the relationships are not always comparable. The paper shows how cultural, migration and socio-economic factors interact to affect the formation of different types of support networks. As a result of a more stable elderly population, more old people in Liverpool have network types able to provide a high level of informal care and support.

City Park

Based on a comprehensive assessment of the state of the park landscape, the level of its anthropogenic transformation is determined, which is necessary to identify the potential for restoring the natural biodiversity of the object. It is reported that the plantations and soil cover of the park of the 50th anniversary of VLKSM are very heterogeneous; they reflect the history of park establishment. The soil cover consists of three main types: sod, bog and urbanozem. It should be stressed that the best preserved part of the park is the plot with boggy soils around the pond. Herbaceous plants growing on the plot are very similar to the species composition of the ground cover of overgrown peat bogs. Over the 40 years since the foundation of the park, a high level of pollutants has been accumulated in the soil, which allows us to state that the negative impact occurs constantly. Consequently, the existing plantings are insufficient to protect visitors from vehicle emissions from the roads along Yasnaya and Shaumyana streets. There are enough natural elements in the park of the 50th anniversary of VLKSM; this should be taken into account in its redevelopment. There is an opportunity to restore the reservoir and return the plantings to their natural appearance. It is proposed to add elements of landscape decoration in the park.

The article deals with one of the most relevant topics of the modern city and ecology - the problem of landscaping in Volgograd. The city is characterized by an industrial urbanism, with a high concentration of population, saturation of production facilities and vehicles, which contributes to a high level of negative impact on the environment. The pace of greening of the city lags behind the pace of construction of the residential sector, and the existing green spaces do not meet the sanitary and hygienic, aesthetic requirements. The prospects of this problem are determined, the existing green spaces are considered, data on the climatic conditions of the city and the ecological situation are given. Improvement in the field of landscaping is associated with the scientifically sound placement of green spaces, taking into account all the factors that affect the growth and development of plants in the urban environment. Unfortunately, due to the uneven distribution of the assortment of trees and shrubs, the species composition of the central streets and squares of the city is extremely poor. The study focuses on the role of the botanical garden in urban landscaping and aims to create recommendations for the sorting of tree and shrub plants for urban landscaping. As a result of the analysis of the assortment of ornamental plants of the open ground of the botanical garden, the article proposed species and varieties of woody and shrubby plants that have passed the introduction tests for more than 5-10 years. Recommendations for sorting are aimed at improving the ecological situation of the city and greening the recreation areas of citizens. The proposed list of tree and shrub species cannot fully solve the problem of greening the city, but it will help to significantly enrich the composition of tree and shrub plants.

AbstractLasioderma serricorne (F.) is a small cosmopolitan beetle regarded as a destructive pest of several stored products such as grains, flour, spices, dried fruit and tobacco. Chemical insecticides are one of the measures used against the pest. However, intensive insecticide use has resulted in the appearance of resistant insect populations. Therefore, for the elaboration of more effective control programs, it is necessary to know the biological aspects of L. serricorne. Among these aspects, the genetic variability knowledge is very important and may help in the development of new control methods. The objective of this study was to evaluate the genetic variability of 11 natural populations of L. serricorne collected respectively in three and four towns in the states of Paraná and São Paulo, Brazil, using 20 primers random amplified polymorphic DNA (RAPD) and polymorphisms of esterases. These primers produced 352 polymorphic bands. Electrophoretic analysis of esterases allowed the identification of four polymorphic loci (Est-2, Est-4, Est-5 and Est-6) and 18 alleles. Results show that populations are genetically differentiated and there is a high level of genetic variability within populations. The high degree of genetic differentiation is not directly correlated to geographical distance. Thus, our data indicate that movement of infested commodities may contribute to the dissemination of L. serricorne, facilitating gene flow.

A morphological study of intra and interpopulation variability of black poplar leaves was conducted in two populations in the area of Vojvodina. Nine morphometric parameters of leaves have been analyzed. The results indicate that there is considerable variability within and between the populations. Morphological differentiation is clearly represented with the average values of analyzed parameters and a statistically significant difference between the mean values. On the basis of the obtained data, it has been concluded that the variability within the two populations is much more expressed than the variability between them. The uniformity of environmental conditions of the studied locations indicates that this variability is a consequence of the specific gene pool of the studied populations.

AbstractA national-scale study in Italy showed an incidence of cancer higher in the territories indicated as highly polluted compared to the regional average. One of them, the city of Taranto in Apulia (Italy), which is considered one of the most polluted cities in Europe, has numerous industrial activities that impact population health. We studied the epidemiological effects of a high level of pollution produced by the industrial area of Taranto in increasing the mortality rate for some specific cancer types in the city and towns of the two provinces located downwind. We analysed 10-year mortality rates for 14 major types of tumours reported among the residents of Taranto, of 6 surrounding towns, randomly placed within an imaginary cone in the main wind direction from the vertex of the industrial zone of Taranto. Our results confirm our hypothesis that the mortality rate for some specific types of cancer (namely, Hodgkin and non-Hodgkin lymphomas, leukaemia, liver and bladder tumours) are higher than the norm in the municipality of Taranto and we have evidence that other local causes may be implicated in the excess of mortality besides the potential dispersal of pollutants from the industrial area of Taranto. The proximity to the industrial area of Taranto cannot, therefore, explain alone the anomalies detected in some populations. It is likely that other site-specific sources of heavy pollution are playing a role in worsening the death toll of these towns and this must be taken into serious consideration by environmental policy-makers and local authorities.

Purpose: I initiate the discussion with a statement about cognitive-cultural capitalism and its concentration in large global cities. This is followed by an argument to the effect that the specificity of the city resides in the manner in which the diverse social phenomena that it contains are brought into a composite pattern of spatial integration. With these preliminaries in mind, I examine the economic structure of the city in cognitive-cultural capitalism, with special reference to the emergence of a new division of labor and the changing configuration of intra-urban production space. This account leads directly to consideration of the restratification of urban society and its effects on neighborhood development and social life. The final section of the paper picks up on the notion of the Common in cognitive-cultural capitalism and offers some speculative remarks regarding the implications of this phenomenon for the economic and social order of cities.Methodology/Approach: Historical and geographical narrative combined with appeals to the theory of political economy.Findings: Cognitive-cultural capitalism is emerging as a dominant force of social and economic change in the twenty-first century. This trend is also evident in new patterns of urbanization that are emerging on all five continents. These patterns reflect dramatic shifts in the structure of urban production systems and the significant restratification of urban society that has been occurring as a consequence.Research Limitation/implication: The paper is pitched at a high level of conceptual abstraction. Detailed empirical investigation/testing of the main theoretical points outlined in the paper is urgently called for.Originality/Value of paper: The paper offers an overall theoretical synthesis of the interrelationships between cognitive-cultural capitalism and processes of urbanization.

The fortifications of Athens have been a recurrent theme of archaeological investigation. In the past two centuries, parts of the walls have been located during rescue interventions at numerous sites in the urban fabric. At present, the visibility of the entire monument remains rather low as the traces of the walls are hidden beneath the modern city, marginalized within larger archaeological sites or preserved entirely by record. Despite the high level of scholarly work devoted to synthesize the available material, the volume of information accumulated over the years requires a novel approach that would systematize different types of evidence using digital media. In this respect, we attempt to revisit the city walls of Athens through the use of geospatial technologies. We target the informed development of an efficient GIS platform to record, store, integrate, explore and eventually disseminate resources on the Athenian fortifications. Our research employs published and archival sources (e.g. excavation drawings) in combination with historical maps (e.g. early cadastral maps, first maps of modern Athens) and complementary historical evidence (e.g. writings, illustrations, photography) to locate, document and integrate in space and time available data on lost and surviving fortification remains.
